Explanation:
If the Universe was born at the Big Bang, what existed before then
Explanation:
In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today.
Or at least, that's what we've been told by physicists for the past several decades.
But new theoretical physics research has recently revealed a possible window into the very early universe, showing that it may not be "very early" after all. Instead it may be just the latest iteration of a bang-bounce cycle that has been going on for … well, at least once, and possibly forever.
Of course, before physicists decide to toss out the Big Bang in favor of a bang-bounce cycle, these theoretical predictions will need to survive an onslaught of observation tests.
The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe.

Which situation is a good example of the transfer of energy through radiation?
A. Energy passes from one person’s hand to another person when they shake hands.
B. A snake’s body temperature increases when the snake lies in the Sun.
C. Warm air that is less dense rises to the ceiling of a room.
D. A fan cools the CPU in a computer.
Radiation has been the mode of thermal energy transfer from a source. "A snake’s body temperature increases when the snake lies in the Sun" is an example of radiation. Thus, option B is correct.
What is radiation?Radiation has been the type by which the thermal heat energy passes from the source to the other site. It has been independent of contact and involves traveling in space with the equivalent speed of light. Unlike conduction and convection, radiation does not need matter.
The particles tend to move in space like the sun's rays heating the earth. When a snake lies in the sun its body temperature rises due to tradition as the solar energy from the sun (high temperature) moved in space to the lower temperature (snake's body).
Therefore, option B. heating the snake's body under the sun is an example of radiation.

Answer:
To study these moths, Dr. Kettlewell placed light and dark moths on the trunks of trees where he could observe them. The same birds would find the dark moth twice as often if the bark on the tree was light. This supported the idea that dark moths had a survival advantage in a dark forest.

Why is the series of reactions in the Calvin cycle called a
"cycle”?
Answer:
You can think of the Calvin cycle as being somewhat like a sugar factory within a chloroplast. It is called a cycle because, like the Krebs cycle in cellular respiration, the starting material is regenerated each time the process occurs. In this case, the starting material that gets regenerated is a compound called RuBP, a sugar with five carbons.
With each turn of the Calvin cycle, there are chemical inputs and outputs. The inputs are carbon dioxide from the air and the ATP and NADPH produced by the light reactions. The Calvin cycle uses carbon from the carbon dioxide, energy from the ATP, and high-energy electrons and hydrogen ions from the NADPH. The cycle's output is an energy-rich sugar molecule. That sugar is not yet glucose, but a smaller sugar named G3P. The plant cell uses G3P as the raw material to make glucose and other organic molecules it needs.
Explanation:
You can follow the process of the Calvin cycle in the figure.
The series of reactions in the Calvin cycle are called a cycle because it involves inputs and outputs.
The Calvin cycle simply refers to the process that algae and plants use in turning carbon dioxide into sugar. The Carbon cycle is made up of steps such as Carbon fixation, reduction phase, carbohydrates formation, and the regeneration phase.
The series of reactions in the Calvin cycle are called a cycle because it involves inputs and outputs. The input molecules are ATP, carbon dioxide, and NADPH. On the other hand, the output molecules are ADP, sugar, and NADP.

Which molecules may diffuse across a cell membrane without the expenditure of energy or the use of membrane proteins?
Explanation:
In simple diffusion, small molecules without charges such as oxygen and carbon dioxide flow through a plasma membrane without assistance and without expending energy. Other substances such as proteins, glucose and charged particles called ions cannot pass through the selectively permeable membrane
Q 9. How do the heart and the lungs work together?
1. What is the Driving Mechanism of Continental Drift?
Answer:
Holmes proposed that the continents, which “floated” on the Earth's mantle, moved with the convection flow of the magma (hot semifluid below the Earth's crust). The mechanism of continental drift is like the flow of branches floating in the moving waters of rivers, as shown in Figure 3-11.4.

A. Is the suspect guilty of the crime?
B. How do you know?
Answer:
A. No
B. because, the suspect doesn't add up to any of the DNA of the killer, victim, or the control, so no the suspect is definetly not guilty and is definetly not the killer. It just wouldn't add up right, none of the other's DNA matches to the suspect, leaving the suspect as not guilty but inisent and doesn't lead or match that suspect to in any way the killer. In other words the killer and suspect don't link in any way!

How do genetics (genetic predisposition) and the environment work together to cause substance abuse in individuals? What is the likely role of epigenetics in this process?
Answer: The drug abuse is influenced by the environment and exerts influence on the gene expressions.
Explanation:
The genetic make up of the person is decides, which genes will be expressed and develop a trait in an individual. But this genetic expression can be influenced by the environmental factors like food, exposure to sunlight, and others. This study which relate environment with the genetic make up is called epigenetics. No person is drug addict by birth but the consumption of drug can influence the genetic make up and traits in a abuser. So here, the environment is influencing the genetic basis of a abuser.

Predict what would happen to the wolf and elk populations if there was a drought that caused many of the plant species to dry up and/or die.
Answer:the elk would die because there would be no plants left and then the wolf would die to because there would be no more elk
Explanation:
If a drought were to cause many plant species to dry up and die, it would have indirect effects on the populations of wolves and elks, which are interconnected through a predator-prey relationship.
The drought leads to a scarcity of water, which affects plant growth. Many plant species, including grasses and shrubs that serve as food sources for elks, dry up and die due to the lack of water.
With the decline in plant food sources, the elk population would face food scarcity. The reduced availability of vegetation would result in limited feeding opportunities for elks, potentially leading to malnutrition and weakened individuals.
Therefore, it's important to note that the specific outcome may vary based on the severity and duration of the drought, the overall ecosystem resilience, and the presence of alternative food sources or migration possibilities for elk and wolf populations.

(BTW if u can let me know if the answer is from google so I can put it in my own words, if it's not also let me know! if you don't it's fine! , works either way!)
Answer:
A control variable is the variable in the experiment that does not change.

PLEASE I NEED HELP Explain how the process of mitosis is essential to the regeneration of tissue using stem cells
Answer:
Mitosis is essential to the regeneration of tissue because during Mitosis, cells replicate to create a daughter cell that is the exact copy of the parent cell.
Explanation:
The reason this is so important is because stem cells can develop into nearly any cell type. Mitosis allows these cells to replicate the exact cell type needed (in this case, tissue), and create a daughter cell that has the same exact components and characteristics of the parent cell.
